How to create, edit and delete podcast episode tags
To add a tag, enter the tag name in the "Add" box and then click the "Add" button.
To edit or delete a tag, pause your cursor on the tag and you'll see the edit and delete icon to edit or delete the tag.
If you delete a tag, you will receive a warning message that any post under that tag will be assigned to the default tag.
